METHOD AND APPARATUS ron M KING ROAD EDGINGS.

Application filed August 10, 1927. Serial No. 212,001.

soon form deep rutsbeside the squared shoulders of the roadway,therebyffrequently making dangerous conditions, and in .any event makingit difiicult for the vehicle to return to the roadway. To. counteractthese conditions, road maintenance forces are constantly employedfilling in the ruts thus made. This is done by hand ,and is not onlyexpensive, but usually the benefit is of short duration and littlevalue, particularly in wet weather.

The object of my invention is to provide an improved method of makingthe road edgings whereby the edgings may be made and maintained at acomparatively low cost. A further object of my invention is to provide amethod of making road edgings which will provide an edging having ampledrainage, thereby maintaining the same in useful con dition for extendedperiods of time, even in bad weather. A further obj ectof my inventionis to provide an apparatus adapted for I use in carrying out. myimproved method.

Other objects will appear hereinafter.

With these objects in view my invention consists generally in a methodof forming road edges which consists in compressing the earth adjacentthe shoulder of the road to form a ditch and then filling the ditch withgravel, cinders or the like which will provide a firm bed for thevehicle wheels, and which will also provide ample drainage. My inventionfurther consists in a device or apparatus for forming the ditch, whichconsists of a rotary member having a V-shaped periphery, which isadapted to be rolled along the edge of the road to compress the earth toform the ditch above mentioned. In carrying out my invention I form thedevice either as part of 1 a truck or other vehicle wheel, or as anattachment to be applied to such wheels. My invention further consistsin various details of construction and arrangements of parts all as willbe fully described hereinafter and particularly pointed out in theclaims.

My invention willbe more readily understood by reference to theaccompanying drawings forming a in which r Fig. l is a verticalsectional view through a truck wheelequipped with anedg'ing 'deviceembodying my invention in one of its part of this specification andforms, and illustrating the same in-the opera-,

Fig. 9 is a side elevation of the device illustrated in Fig. 8.

Referring 'now' to Fig. indicates conventionally a truck wheel to whichis secured an apparatus embodying my invention for forming aditch alongthe side of the concrete slab 2 of a roadway, the slab having the usualsquare or vertical shoulder 3. The device comprises a circular member 4'having a wedge shaped periphery 5, which projects radially beyond thetread of the truck wheel the depth it is desired to form the ditch 6along the side. of the road. The device l is secured to the truck wheelin any desired manner, as-by bolts 7, access to the bolts being hadthrough apertures. 8.

In using the device the truck or other vehicle to which the ditchingdevice isapplied, is driven along the roadway with member 4 justclearing the shoulders 23. The weight of the vehicle causes the wedgeshaped portion to compress a ditch6 along the side of the roadway. Incompressing this ditch it should be noted that the earth is greatlycompressed about the ditch as indicated at 9, which is greatly conduciveto the long life of the edging. After the ditch is formed it is filledwith coarse material, such as cinders or 1 of the drawings, 1

gravel, such material not only making a good but also providing V unitartions,

-V-shaped peripheral extension. In this form of thedemice L1 indicatesthetnead at the wheel which is adapted to travel on the road- Way and 12the V-shaped extension formed 7 integrally therewith.

In the form of the deyice illustrated in Fig 1, the wheel attachment 4is substantially an structure. If preferred, the extension 5 may beformed in sec- .asillustrated in Figs. 5 and 6, eaeh section beingformed with a flange 13 adapted to be seuredto-the tread 14 of the wheelby shape bolts 15. Fig. 7 illustrates a construction sired manner,either integrally With the wheel of the Vehicle with which it is to beused, or formed to be attached to any ordinary or special form otwheel;Also, it may be madeas an unitary structure or made in sections, It isalso obvious that in carrying out my improved methodufimtk'mgmededgumggaxnore permanent edging may be made and maintained at a lowercost than methods now employed.
